The RSH2 series from RECOM - a series of compact, high efficiency, 2W DC/DC converters in a surface-mount format with wide input ranges.

RECOM has added to its DC/DC converter range the RSH2 series - a fully regulated, low noise, isolated 2W DC/DC converter in a surface mount package. The series features nominal inputs of 3.3V (2.8-5.5V), 5V/9V (4.5-13.2V), 12V (9-18V), and 24V (18-36V), useful for battery or bus-powered systems.

The outputs available are 3.3V, 5V, 12V, 15V, and 24V. The parts have short-circuit and overcurrent protection, and they meet EN 55032 class A or B limits for input noise with a simple external filter. No minimum load is required, and on/off control is standard.

The RSH2 series operates from -40°C to 85°C without derating, making the product suitable for demanding industrial, test and measurement, and transport applications.

The isolation rating is 2kVDC/60s (optionally 3kVDC/60s) with UL/IEC/EN 62368-1 certification. The parts are RoHS-2 compliant.

The RSH2 series comes in a compact, lightweight DIP14 SMD case, available in tube or tape-and-reel packaging. The parts may be IR-oven or vapor-phase reflow soldered using industry-standard JEDEC profiles.

Matthew Dauterive, DC/DC Product Manager of RECOM comments ‘The surface mount RSH2 series is a perfect way to generate isolated on-board power rails in mains and battery powered equipment. The RSH2 will also find use in ground-loop isolation for industrial sensors and bus communication networks’.

The RSH2 series is available through all authorised RECOM distributors or direct contact with the manufacturer. Samples can be requested via the RECOM website.
